Ich hatte das Konzept so verstanden, dass herkömmliche Abmessungen von Sensorpixels durch Jods ersetzt werden.
Dann kämen pro Pixel 4225 Jods zum Einsatz und eine entsprechende Sensorgrösse.
Geht aber natürlich auch anders.
Zum Thema Rauschen...
„The best measured device (the “golden jot”) showed conversion gain after the in-pixel SF of 423μV/e-, and read noise as low as 0.22e- r.m.s. at room temperature with a single CDS readout. Dark current is less than approximately 0.1e-/s at room temperature in the 1.4μm pitch devices.“
Was die Optik betrifft, bin ich mir nicht ganz sicher, ob man überhaupt noch eine Optik (im konventionellen Verständnis) braucht. (??)
Vielleicht hat Rudi dazu genauere Informatuonen ?

„After the QIS concept was introduced in 2005, the concept was applied for use with single-photon avalanche detectors (SPADs) by the group at the University of Edinburgh [27–30] as published starting in 2014 as part of their SPAD research program. Other work on SPADs published in 2005 shows concurrent conception of some of the same ideas [31], and
in 2009 a “gigavision camera” using binary pixels was proposed by researchers from École Polytechnique Fédérale de Lausanne (EPFL) “

Recently we have proposed a new image device called the gigavision camera. The main feature of this camera is that the pixels have a binary response. The response func- tion of a gigavision sensor is non-linear and similar to a logarithmic function, which makes the camera suitable for high dynamic range imaging. Since the sensor can detect a single photon, the camera is very sensitive and can be used for night vision and astronomical imaging.
One important aspect of the gigavision camera is how to estimate the light intensity through binary observations. We model the light intensity field as 2D piecewise con- stant and use Maximum Penalized Likelihood Estimation (MPLE) to recover it. Dynamic programming is used to solve the optimization problem. Due to the complex com- putation of dynamic programming, greedy algorithm and pruning quadtrees are proposed. They show acceptable re- construction performance with low computational complex- ity. Experimental results with synthesized images and real images taken by a single-photon avalanche diode (SPAD) camera are given.„
„Außerdem ist der besprochene Sensor s/w, es kann keine farbigen Testaufnahmen geben.“
Jeder Sensor ist s/w und kann keine farbigen Aufnahmen machen.
